Server Instance Introspection for Shared Resource Collisions Using Call Stack Dependencies

2. The non-transitory computer-readable medium of claim 1, wherein the first call stack comprises a string that represents a status of an associated thread, and the status indicates that the associated thread holds the lock on the memory location.

3. The non-transitory computer-readable medium of claim 1, wherein the second call stack comprises a string that represents a status of an associated thread, and the status indicates that the associated thread is waiting for the memory location to be available after the lock on the memory location is released.

4. The non-transitory computer-readable medium of claim 1, wherein a third call stack comprises a string that represents a status of an associated thread, and the status indicates that the associated thread is waiting to be assigned a job by the server instance.

6. The non-transitory computer-readable medium of claim 5, wherein the list of jobs is stored locally by a process that executes on a second server instance.

9. The non-transitory computer-readable medium of claim 1, wherein the memory location comprises a shared memory in the server instance that is shared between the job kernels.

10. The non-transitory computer-readable medium of claim 9, wherein the adjustment of the configuration comprises increases a shared memory threshold for the server instance that determines when values are stored to the shared memory instead of being passed between threads.

11. The non-transitory computer-readable medium of claim 1, wherein triggering the adjustment of the configuration comprises sending a notification of the adjustment to a user of the server instance.

12. The non-transitory computer-readable medium of claim 1, wherein triggering the adjustment of the configuration comprises automatically changing the configuration of the server instance without requiring human intervention.

13. The non-transitory computer-readable medium of claim 1, wherein the memory location comprises a shared disk of the server instance that is shared between the job kernels.

14. The non-transitory computer-readable medium of claim 13, wherein the adjustment of the configuration comprises creating a new server instance to reduce a number of jobs waiting to be assigned to kernels that prepare or use the shared disk.

15. The non-transitory computer-readable medium of claim 13, wherein the first call stack is associated with a first thread executing in a metadata kernel, and the second call stack is associated with a second thread executing in a batch kernel.

17. The non-transitory computer-readable medium of claim 1, wherein accessing the plurality of call stacks occurs in response to a determination that a performance metric of the server instance is below a threshold level of performance.

18. The non-transitory computer-readable medium of claim 17, wherein the determination that the performance metric of the server instance is a real-time determination, and the adjustment of the configuration is triggered as the server instance operates.
